Mercedes-Benz CLA with EQ Technology (C174) (C174)

The C174 is the first Mercedes-Benz built on MMA, and the first to treat an 800-volt compact car with almost 800 kilometers of range as a matter of course rather than a headline.

Unveiled in Rome on 13 March 2025, it inverted the compact-car formula the CLA had followed since 2013: the main drive unit sits at the rear axle, not the front. That unit is a permanently excited synchronous motor derived directly from the VISION EQXX, with double-V rotor magnets, hairpin stator windings, almost no heavy rare earths and a silicon-carbide inverter integrated with the transmission control. Battery-to-wheel efficiency over long distances is 93 per cent. Behind it sits the detail that separates the CLA from every other electric Mercedes-Benz: a two-speed transmission, 11:1 for standing starts and city work, 5:1 for the autobahn, where the electronically limited 210 km/h is reached in second.

An 85 kWh nickel-manganese-cobalt pack, 320 kW DC charging and a drag coefficient from 0.21 give the CLA 250+ up to 792 km on the WLTP cycle — enough that the range conversation stopped being about anxiety and started being about tires and wheel covers. The range has since widened downwards to a 58 kWh lithium-iron-phosphate CLA 200 and upwards to the Mercedes-AMG CLA 45 4MATIC+, which replaced the hand-built M139 four with three axial-flux motors and 500 kW. In January 2026 the CLA was named European Car of the Year, the first Mercedes-Benz to take the title since the 450 SE in 1974.

Year by year.

From the Concept CLA at the 2023 IAA to European Car of the Year and an electric AMG 45 — the milestones of the MMA era.

  1. 2023
    • Concept CLA shown at IAA Mobility in Munich in September, previewing the MMA platform, the 800-volt architecture and the star-pattern grille that reached production almost intact.
  2. 2025
    • World premiere in Rome on 13 March as the first Mercedes-Benz on the Mercedes Modular Architecture, and the first car to run entirely on MB.OS — QNX for the cluster and safety functions, Linux for infotainment.
    • European sales open on 29 April with the CLA 250+ (200 kW, rear-wheel drive) and the CLA 350 4MATIC (260 kW), both on an 85 kWh NMC pack charging at up to 320 kW.
    • CLA L, four centimeters longer in the wheelbase and overall, shown at Auto Shanghai in April and sold in China from September.
    • October: the CLA 200 with EQ Technology joins with a cheaper 58 kWh lithium-iron-phosphate pack, 165 kW and 542 km WLTP.
    • December: five stars from Euro NCAP, the highest-scoring car the organization tested that year.
  3. 2026
    • 9 January: named European Car of the Year at the Brussels motor show with 320 points, ahead of the Škoda Elroq and Kia EV4 — the first Mercedes-Benz to win since the 450 SE took the 1974 title.
    • February: the CLA 250 with EQ Technology arrives between the two extremes, with a 71 kWh NMC pack, 250 kW charging and 674 km WLTP.
    • Spring: a factory-fitted DC-DC converter becomes available, finally allowing the 800-volt CLA to charge at 400-volt stations.
    • 9 July: Mercedes-AMG CLA 45 4MATIC+ revealed with three axial-flux motors — two in the rear High Performance Electric Drive Unit, one at the front with a Disconnect Unit — for 500 kW peak, 450 kW continuous and 1,759 N·m. The M139 four-cylinder is not replaced.
